This Crystal Black Double Glazed Window is designed for homeowners seeking to enhance natural light and energy efficiency. Its primary benefit is improved thermal insulation, potentially lowering energy bills. A caveat is that installation may require professional expertise. Key features include A-rated energy efficiency, low U value, Low E glazing with argon gas, and a secure espag locking system, all presented in a sleek black frame with a white handle.

It means that when viewed from the outside, the window opens outwards from the right side (side hung) and also has an additional tilt opening at the top.
The Low E coating is on the inner surface of the glass. Clean it gently with a soft, damp cloth and mild, non-abrasive soap. Avoid scrubbing or using harsh chemicals.
Yes, its A-rated energy efficiency and low U value make it suitable for most climates, helping to regulate indoor temperatures year-round.
A 'Warm Edge' spacer bar is made of less conductive material than traditional metal spacers, reducing heat transfer around the perimeter of the double-glazed unit, thus improving insulation.
While minor DIY skills might suffice for some tasks, professional installation is highly recommended to ensure proper sealing, security, and optimal energy efficiency performance.
Trickle vents are small openings, often integrated into the window frame, that allow a small, controlled amount of air to pass through even when the window is closed. This helps reduce condensation and improve air quality.
The U value measures how well a window insulates. A lower U value (like 1.4 W/m²K for this window) indicates better insulation, meaning less heat is lost through the window, leading to energy savings.
Check for obstructions around the frame or sash. Ensure the espag locking mechanism is fully disengaged. The window may need adjustment by a professional if warped or misaligned.
Ensure the trickle ventilation is open and not blocked by debris. Improve room ventilation by opening windows regularly or using extractor fans. Persistent condensation may indicate a seal failure, requiring professional inspection.
Check the seals around the window and cill for damage or gaps. Ensure the window is properly secured. Minor gaps can sometimes be sealed with appropriate caulk, but significant drafts may indicate an installation issue.
Clean and lubricate the espag locking mechanism with a suitable lubricant. Ensure no debris is obstructing the moving parts. If stiffness persists, consult a window specialist.
Setup: Installation of this window is recommended to be carried out by a qualified professional to ensure proper fitting, sealing, and operation, especially to maximize its energy efficiency benefits. Ensure the opening is precisely measured to match the window's dimensions of 1190mm x 1190mm.
Compatibility: This window is designed as a right-hand side-hung and top-opening unit when viewed from the outside. Confirm this configuration suits your intended installation location. It is suitable for most modern residential applications.
Care: Clean the glass surfaces regularly with a soft, damp cloth and mild detergent. Avoid abrasive cleaners that could scratch the glass or frame. The PVC cill and black frame can be wiped clean with a damp cloth. Periodically check the espag locking mechanism and lubricate moving parts if necessary. Ensure the trickle vents are kept clear of debris to maintain airflow.
